npm run <script>

stop

Stops the adz-pdf-export service

remove

Troubleshooting

If pdfs are not downloading, there are a few things that you should check first

Is the service running? Open windows Task Manager, click on the services tab and find adz-pdf-export service.
If the service is running, check the logs on Stackify to see further information
If the service is not running, right click and press Start.
If the service remains in paused mode even after attempting to start the service via task manager, then you should check windows event logs
to debug. Check any errors or warnings that have a value of nssm in the source column.
